Subject: [PATCH AUTOSEL 4.9 2/2] ARC: Fix CONFIG_STACKDEPOT
Date: Mon, 16 Aug 2021 20:36:25 -0400 [thread overview]
Message-ID: <20210817003625.83589-2-sashal@kernel.org> (raw)
In-Reply-To: <20210817003625.83589-1-sashal@kernel.org>
From: Guenter Roeck <linux@roeck-us.net>
[ Upstream commit bf79167fd86f3b97390fe2e70231d383526bd9cc ]
Enabling CONFIG_STACKDEPOT results in the following build error.
arc-elf-ld: lib/stackdepot.o: in function `filter_irq_stacks':
stackdepot.c:(.text+0x456): undefined reference to `__irqentry_text_start'
arc-elf-ld: stackdepot.c:(.text+0x456): undefined reference to `__irqentry_text_start'
arc-elf-ld: stackdepot.c:(.text+0x476): undefined reference to `__irqentry_text_end'
arc-elf-ld: stackdepot.c:(.text+0x476): undefined reference to `__irqentry_text_end'
arc-elf-ld: stackdepot.c:(.text+0x484): undefined reference to `__softirqentry_text_start'
arc-elf-ld: stackdepot.c:(.text+0x484): undefined reference to `__softirqentry_text_start'
arc-elf-ld: stackdepot.c:(.text+0x48c): undefined reference to `__softirqentry_text_end'
arc-elf-ld: stackdepot.c:(.text+0x48c): undefined reference to `__softirqentry_text_end'
Other architectures address this problem by adding IRQENTRY_TEXT and
SOFTIRQENTRY_TEXT to the text segment, so do the same here.
